18-year-old builds one-man DIY submarine out of a drainpipe

Justin Beckerman wasn't your ordinary high school student. Instead of planning for prom night, Beckerman was taking rides in a one-man submarine he built from the ground up when he was just 18 years old. Referred to as the teenage Thomas Edison , the New Jersey resident spent one month designing and five months building his nine-foot-long submarine . The submarine can dive as deep as thirty feet, giving Beckerman plenty of room to explore Lake Hopatcong—in between crew team practice and homework, of course.
